Abstract: FIELD: molecular biology, biochemistry. SUBSTANCE: invention relates to method of electrochemical assay of events of sequence-specific hybridization of oligomers of nucleic acid. For this purpose, single-stranded oligomeric DNA, RNA or PNA are bound by their end with surface of a carrier and by another free end they are bound covalently with oxidative-reducing pair and used as hybridizing matrix (probe). As result of treatment with solution of oligonucleotide (target) to be studied the electric bind between conducting surface of carrier and oxidative- reducing pair that are bound by a single-stranded oligonucleotide being the latter is absent or weak initially is subjected for modification. In the case of hybridization this electric bind between surface of carrier and oxidative-reducing pair that are bound now by hybridized single-stranded oligonucleotide is enhanced. This allows to assay events of hybridization using methods of cyclic voltammetry, amperometry or measurement of conductivity. EFFECT: improved preparing method. 51 cl, 9 ex

Abstract: FIELD: printing by printing ink, in particular, printing on cans, as well as the system for application of printing ink designed for printers. 
     SUBSTANCE: in the system for application of printing ink designed for the form cylinder the belt used for transfer of ink transfers ink from the roller, which receives ink from the source of its delivery to the elements for production of ink on the form cylinder. The great number of guide rollers from the inner side of the belt loop gets engaged with the drive surface of this belt. The drive is connected to one of the guide rollers for putting it in rotation at the first speed, which represents the roller speed for transfer of ink and the form cylinder. The roller for ink distribution is located on the outer side of the belt loop in contact with the opposite one transferring ink by the belt surface, and between the roller for transfer of ink and the form cylinder. 
     EFFECT: minimized areas of contact between the rollers, reduced separation of ink, ejection of ink by the rollers and fog produced by it, as well as prevented or reduced appearance of the effect of "shades" or "corona" at printing.
